Heat Sealers

Heat Sealers are used to seal thermoplastic materials using heat generated from resistance wires, ribbons or strip that are typically made from Nichrome or nickel chrome materials. Heat sealing can join similar thermoplastic materials or can join different materials as long as one has a thermoplastic layer.

There are principally 2 types of heat sealers:

Impulse (for sealing similar materials), in which a low voltage electric current is applied for a specified time and pressure is applied to make the seal

Constant (for sealing dissimilar materials), in which the heated tooling is kept at a constant temperature.

Typical applications are packaging and bag sealing.
